application filed July 11, 1918. serial No. 24:4,l56.

from a locking device which will resist the may be held upon the body releasably.

lit is within the province of the disclosure to improve generally and tov enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in elevation, a padlock constructed in accordance with the invention, parts being shown in section, Fig. 2 is a section on the line i k-13 of Fig. 1, looking in the direction of the arrow marked 2; Fig. 3 is a section on the line A.-B of Fig. 1, looking in the direction of' the arrow marked 3; Fig. 4c is a top plan of the body, the shackle removed.

The device forming the subject matter of this application preferably, but not necessarily, is fashioned from metal throughout,

a back 3 and a marginal rim 4. In the rim 4, a first opening 5 is formed, the constituent metal of the rim being bent inwardly, along one edge of the opening 5 to form an lntegral keeper 6. In the rim 4, a plurality of second openings 7 are formed. The invention comprises a U-shaped resilient shackle 8, one end of which, as shown at 9, is threaded through the second openings 7, and 1S permanently held therein. The other end of the shackle is extended through the first opening 5 and is terminally provided with an integral finger 10, adapted to engage the keeper 6, the keeper 6 and the finger constituting interlocking elements.

The end of the shackle 8 which carries the finger 10 maybe inserted readily through the opening 5, the resiliency of the shackle causing the finger 10 to interlock with the keeper 6. It is possible, however, to detach the finger 10 from the keeper 6 and to withdraw the free end of the resilient shackle from the opening 5, by flexing the shackle 8 slightly.

The device forming the subject matter of this application obviously is made of two pieces only, and may be turned out at slight expense, the structure not only being useful as a locking means, but, in addition, having utility, in that it may be used as an inexpensive advertising device, which may be given away.

Having thus described the invention, what is claimed is A two-piece padlock comprising a body including a rim having a first opening, and provided with an integral keeper located at one edge of the opening, the rim being provided with a plurality of second openings; and a spring shackle having one of its ends sinuously arranged in the second openings and permanently held therein by said sinuosity, the other end of the shackle being removably mounted in the first opening, and terminating in an integral angular finger releasably engaged with the keeper.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
